| abstract |
A multi-component vaccine composition is described comprising acellular pertussis vaccine components, diphtheria toxoid, tetanus toxoid and inactivated poliovirus. The composition also may contain a conjugate of a capsular polysaccharide of Haemophilus influenzae type b and tetanus toxoid or diphteria toxoid, which may be reconstituted from a lyophilized state by the other components of the vaccine. The administration of the multiple component vaccine results in no diminution in the immunogenicity of any component as a result of interference by other components of the vaccine. |
